Addresyo Lock is a Shopify app designed for merchants who prefer not to have their customers' default address automatically updated to the shipping address after placing an order. Instead, this app ensures the default address is updated to the billing address, providing more control and accuracy for merchant operations. It seamlessly integrates with Shopify's existing infrastructure, leveraging customer details such as address, name, and phone number, all of which remain securely stored on Shopify's servers. One of the standout features of Addresyo Lock is its ability to function within Shopify Flow, making it easy to use and manage without any complex configurations. Merchants have the flexibility to manually adjust or edit default addresses as needed. Importantly, Addresyo Lock is designed with security in mind, ensuring no customer data is stored by the app itself.
